The premier said the MP gave a detailed explanation before new allegations were referred to police.

"Because of that police investigation, I will not be making any further comment," Ms Palaszczuk said, trying to head off the pressure.

But even after Question Time ended the opposition continued to pile the pressure on.

Ms Miller's favourite political sparring partner Jarrod Bleijie capped off the day by referring her to the police and the Crime and Corruption Commission.

"I formally ask that you direct your officers to consider whether there has been any breach of the criminal laws of Queensland by the Minister for Police's invention in this matter," the opposition police spokesman wrote.

Police have told AAP they are still "considering" the allegations against Mr Williams but have not launched an official investigation.
